Figure 3From: Genome-wide discovery and characterization of maize long non-coding RNAsCharacteristics of maize lncRNAs. (A) Distribution of lncRNAs along each chromosome. The abundance of HC-lncRNAs, pre-lncRNAs and FGS genes in physical bins of 10Â Mb for each chromosome (generated using Circos). (B) Proportion of HC-lncRNAs and pre-lncRNAs that are located within 5Â kb (upstream or downstream) or further than 5Â kb from the nearest FGS gene. The proportion of FGS genes located within close proximity to other FGS genes is used as a control. (C) Lengths of HC-lncRNAs, pre-lncRNAs and FGS transcripts. (D) Numbers of exons in HC-lncRNAs, pre-lncRNAs and FGS. (E) Percentage of maize HC-lncRNAs and FGS transcripts that are conserved in the Arabidopsis, rice and sorghum genomes compared with the sequence conservation of intergenic or intronic fragments among species. Sequences were repetitive-sequence masked and aligned to the genomes of Arabidopsis, rice and sorghum with the significant cutoff E value <1.0E-10.Back to article page
